Comment (by mikeschroder):

 I reached out in #core-editor (linked above), then in
 https://github.com/WordPress/gutenberg/pull/11973 as a followup, as I
 noticed that the PR is not merged and does not have a milestone.

 As far as I can tell, some way for the editor to provide the attributes
 (whether the above PR, or a different approach) will still need to land in
 Gutenberg before the [attachment:"45407.diff" core patch on this ticket]
 will be helpful.
